This function creates a URL with signed query parameters for a file upload. It includes required and optional parameters, calculates an expiration time, encodes the URL, and appends an HMAC-SHA256 signature to ensure secure access to the upload endpoint. Args: region_alias (str): The region alias to be used in the URL (e.g., "us-east"). This is a subdomain for the base URL. file_key (str): The unique file key or identifier used in the URL path. api_key (str): The API key used to generate the HMAC-SHA256 signature. app_id (str): The application identifier. file_name (str): The name of the file being uploaded. file_size (int): The size of the file in bytes. file_type (str | None, optional): The MIME type of the file. custom_id (str | None, optional): An optional custom identifier for the file. content_disposition (str | None, optional): Content disposition directive. acl (str | None, optional): Access control list setting for the file. Returns: str: A fully constructed pre-signed URL including the signature that can be used to securely upload the file. ii6)expireszx-ut-identifierzx-ut-file-namezx-ut-file-sizezx-ut-file-typezx-ut-custom-idzx-ut-content-dispositionzx-ut-aclzhttps://z.ingest.uploadthing.com/?z &signature=)inttimer hmac_sha256)rrrrrr r r r r rparamsbase_urlencoded_paramsurl signatureurl_with_signatures P/var/www/Befach/backend/env/lib/python3.12/site-packages/upyloadthing/presign.pymake_presigned_urlrsP$))+$%6G!## F#, #, -@)*  z,'?zJHv&NJa' (CC)I 5 I;7 rc|jd}|jd}tj||tj}|j }d|S)a Calculates the HMAC-SHA256 signature of the given URL.
